Description of template class 'Labels'
This class is useful to stores a set of numbers as a characteristic set. It is very similar to a bitset, except it provides more functions, like giving the index of a label (i.e., if (1, 5, 6, 13, 20) are the labels, then 1 has index 0, 5 has index 1, 6 has index 2, 13 has index 3, 20 has index 4.)
| L | is the maximum number of labels. |
| TWord | the integer used to store the labels (if L >= log_2( digits( TWord ) ) then several consecutive words are stored.) |

| DGtal::Labels< L, TWord >::~Labels | ( | ) |
Destructor.
| DGtal::Labels< L, TWord >::Labels | ( | ) |
Constructor.
| DGtal::Labels< L, TWord >::Labels | ( | const Self & | other | ) |
Copy constructor.
| other | the object to clone. |

| ConstIterator DGtal::Labels< L, TWord >::end | ( | ) | const |
| Self & DGtal::Labels< L, TWord >::flip | ( | Label | l | ) |
Flips l in or out of the set.
| l | any label in 0..L-1 |
| void DGtal::Labels< L, TWord >::getLabels | ( | std::vector< Label > & | labels | ) | const |
As output, labels[0] contains the label of index 0, labels[1] the label of index 1, and so on.
| labels | (modified) the (ordered) labels set. |
| SizeType DGtal::Labels< L, TWord >::index | ( | Label | l | ) | const |
| l | any label in 0..L-1 |
| bool DGtal::Labels< L, TWord >::isValid | ( | ) | const |
Checks the validity/consistency of the object.
| Self & DGtal::Labels< L, TWord >::operator= | ( | const Self & | other | ) |
Assignment.
| other | the object to copy. |
| Self & DGtal::Labels< L, TWord >::reset | ( | ) |
Clears the set.
| Self & DGtal::Labels< L, TWord >::reset | ( | Label | l | ) |
Removes l from the set.
| l | any label in 0..L-1 |
| void DGtal::Labels< L, TWord >::selfDisplay | ( | std::ostream & | out | ) | const |
Writes/Displays the object on an output stream.
| out | the output stream where the object is written. |
| Self & DGtal::Labels< L, TWord >::set | ( | Label | l, |
| bool | val = true |
||
| ) |
If val is true, inserts l in the set, otherwise removes it.
| l | any label in 0..L-1 |
| val | either true or false. |
